Detailed Description

An automatic cotton mixer as shown in fig. 1-7 comprises a frame, a cotton mixer body 1 arranged on the frame, and a dust removing device 2 for cleaning the fly generated by the cotton mixer body 1. The top of cotton mixer main part 1 sets up feeder hopper 3, feeder hopper 3 communicates with feed inlet 4 of cotton mixer main part 1. The frame comprises a chassis 5 and two vertical side frames 6 arranged on the chassis 5. That is, the invention generally comprises a cotton mixer body 1, a dust removal device 2 and a feed hopper 3, wherein the cotton mixer body 1 is used for mixing various fiber raw materials, the dust removal device 2 is used for removing impurities such as dust, broken fibers and the like generated in the mixing process, and the feed hopper 3 is used for improving the automation of the feeding of the cotton mixer 1. The improvement of the invention is mainly reflected in three aspects: 1. a cotton mixer main body 1; 2. a dust removing device 2; 3. a feed hopper 3. Each improved point can be independently applied to the existing cotton mixer, certainly, the improved points can be combined in pairs, and even three improved points are combined together and applied to the cotton mixer.

From the improvement of the cotton mixer main body 1, as shown in fig. 1, the cotton mixer main body 1 of the invention comprises a mandrel 7, a mixing drum 8 and an outer drum 9, wherein the mandrel 7, the mixing drum 8 and the outer drum 9 are arranged in sequence from inside to outside. The mandrel 7 extends in the transverse direction, and two ends of the mandrel are fixedly arranged on the side frames 6. The mixing drum 8 is coaxially sleeved outside the mandrel 7 and forms a rotating fit with the mandrel 7, namely, the mandrel 7 of the invention is fixed, and the mixing drum 8 can rotate. Regarding the installation manner of the mixing drum 8, the present invention preferably adopts, as shown in fig. 1 and 3, that two annular installation grooves 17 are provided on the circumferential surface of the mandrel 7, the installation grooves 17 are located opposite to the two ends of the mixing drum 8, and the two ends of the mixing drum 8 are connected with the mandrel 7 through bearings 18 disposed in the installation grooves 17, and the installation grooves 17 may be selectively protruded from the surface of the mandrel 7 or may be in a concave form. Such a matching mode enables the mixing drum 8 to rotate more smoothly and is not easy to generate position shifting on the mandrel 7. Of course, it is also possible to fit the mandrel 7 and the mixing drum 8 in place in other ways that serve the same purpose.

A mixing roller 8 of the cotton mixing machine main body 1 is driven by a first motor 10, and a mixing mechanism is arranged in the mixing roller 8. Conventional driving means are for example: the mixing drum 8 is provided with a ring gear on the circumferential surface thereof, and the power of the first motor 10 is transmitted to the mixing drum 8 by a gear engaged with the ring gear. However, considering that the present invention needs to install the outer cylinder 9, in order to avoid interference, it is preferable that a coupling head 19 is disposed at one end of the mixing drum 8, i.e. the end surface at the right end in fig. 2, and the coupling head 19 is tubular to avoid interference with the mandrel 7. A ring of toothed rings 20 is arranged on the circumferential surface of the connecting head 19. The first motor 10 is fixedly arranged on the chassis 5, and a gear 21 is arranged at the power output end of the first motor 10. The gear 21 is in transmission connection with the toothed ring 20 through a first belt 22.

Regarding the installation of the outer cylinder 9, the bottom of the outer cylinder 9 is fixedly arranged on the chassis 5 through the underframe 11, and the outer cylinder 9 is coaxially sleeved outside the periphery of the mixing drum 8 and forms a rotating fit with the mixing drum 8, that is, the mixing drum 8 and the outer cylinder 9 can also relatively rotate, but the air tightness of the joint between the mixing drum 8 and the outer cylinder 9 should be ensured, and the simplest sealing mode is to fill lubricating oil in the gap between the mixing drum and the outer cylinder to form oil film sealing. It is of course also possible to provide an elastic seal in the gap between the two, which is fixed on the one side to the mixing drum 8 and on the other side bears against the outer drum 9. Of course, other ways of forming the seal are possible, and the seal structure will not be described here again for simplicity. The feed inlet 4 of the cotton mixing machine main body 1 is positioned at the top of the outer barrel 9. As shown in fig. 4 and 6, the mixing drum 8 of the present invention is uniformly provided with a plurality of fiber inlets 12 on the circumferential surface, and a stripping plate 13 is provided at each fiber inlet 12. The stripping plate 13 extends from one end of the fiber inlet 12 to the other end in an inclined manner, and a fiber catching port 14 is formed between the outer end of the stripping plate 13 and the mixing drum 8 and used for collecting loose fiber bundles and fiber bundles in the mixing drum 8. In fig. 4, when the mixing drum 8 rotates clockwise, the fiber catching port 14 is oriented in the clockwise direction as well as the rotation direction of the mixing drum 8, the outer surface of the peeling plate 13 is provided with first pins 15, and the inner wall of the circumferential surface of the outer cylinder 9 is provided with second pins 16.

In the process of mixing fibers, various fibers are added from a feed hopper 3 and enter the cotton mixer main body 1 from a feed inlet 4, a first motor 10 is started to drive a mixing roller 8 to rotate continuously, and a stripping plate 13 also rotates continuously in the rotating process of the mixing roller 8; the stripping plate 13 continuously strips the fibers at the feed inlet 4 and dispersedly entrains the fibers between the outer cylinder 9 and the mixing drum 8. The agglomerated and conglomerated fibers are torn by the first needle teeth 15 and the second needle teeth 16 and are further opened into fluffy and dispersed fiber bundles, and certain premixing is also completed in the process; meanwhile, the first needle teeth 15 and the second needle teeth 16 have certain carding function on the fiber raw materials, so that the interlinkage among the fiber yarns can be weakened, and the subsequent mixing is more convenient. After being processed by the first needle teeth 15 and the second needle teeth 16, the dispersed and fluffy small bundles and small bundles of fibers enter the mixing drum 8 through the fiber catching port 14 and the fiber inlet 12 in sequence in the rotation process of the mixing drum 8 to be mixed for the second time, and at the moment, the various fibers have better mixing uniformity. Compared with the traditional cotton mixer, the invention can loosen the conglomerated and blocky fiber raw materials and improve the adaptability to the raw materials and the mixing uniformity. Meanwhile, the cotton mixing machine main body 1 is compact in structure, multipurpose and small in occupied area.

The mixing mechanism arranged in the mixing roller 8 of the cotton mixer main body 1 can be a rod-type stirring paddle, an adaptive beater and the like, but more preferably, the mixing mechanism comprises a plurality of mixing barbed rods 23 extending along the length direction of the mixing roller 8 and beating rods arranged on the mandrel 7 and extending along the radial direction of the mandrel 7, and two ends of the mixing barbed rods 23 are fixedly connected with two end faces of the mixing roller 8 respectively. As shown in fig. 4, the number of the mixing sticks 23 is 4, but may be more. In the process of the continuous rotation of the mixing drum 8, the fiber raw materials are continuously stirred and mixed under the combined action of the mixing pricker rod 23 and the beating rod.

Because different fibers have larger difference of rigidity to stirring, on the basis, the fiber damage is reduced and the universality is improved. The cotton mixer main body 1 of the present invention has a better structure that the mixing pricker 23 is made of rubber, the mixing pricker 23 comprises a pricker body 24 and a pricker body 25 arranged on the surface of the pricker body 24, and the pricker body 25 is composed of a conical bottom section and a spherical top section. Thus, the stick body 24 and the thorn body 25 have certain flexibility, and compared with the conventional rigid hook thorn, the textile fiber damage can be effectively realized, and the method is particularly suitable for mixing long fiber raw materials. An inflation cavity extending along the length direction of the stick body 24 is arranged in the center of the stick body 24, a valve core 26 is arranged at one end of the mixing stick 23, and the operating end of the valve core 26 is positioned on the outer wall of the end face of the mixing drum 8. Thus, the valve core 26 can inflate and deflate the interior of the stick body 24, thereby adjusting the hardness of the hybrid pricker stick 23, for example: when the inflation is saturated, the hardness is higher; if the amount of inflation is small, the hardness becomes small. Therefore, the fiber material can adapt to fiber raw materials of different materials, and has an adjusting function in a certain range.

Of course, after the mixing is completed, in order to facilitate the taking out of the fibers, the outer discharge door 27 and the inner discharge door 28 which can be opened and closed are provided on the peripheral surface of the lower side portion of the outer cylinder 9 and the peripheral surface of the mixing drum 8, respectively. After the outer discharging door 27 is opened, the inner discharging door 28 is rotated to a position opposite to the outer discharging door 27, and the raw material can be removed by opening. Of course, it is also possible to provide the discharge door in other positions, or to achieve continuous discharge by continuing the improvement. In order to facilitate the maintenance of the interior of the mixing drum 8, the end face of one end of the mixing drum 8 is also provided with an openable access door 29, and the arrangement of the access door 29 should not affect the sealing performance of the mixing drum 8.

Besides, another difference of the invention in the aspect of the cotton mixer main body 1 is that a shaft cavity 30 is arranged inside the mandrel 7 along the length direction of the mandrel 7, that is, the mandrel 7 is a hollow shaft, a shaft hole 31 communicating the outside of the mandrel 7 and the shaft cavity 30 is arranged on the circumferential surface of the mandrel 7, and a layer of stainless steel filter screen 32 is arranged on the inner wall of the mandrel 7. One end of the mandrel 7 is provided with a pumping and discharging port communicated with the shaft cavity 30, the pumping and discharging port is communicated with a negative pressure device, the negative pressure device is used for pumping and discharging gas inside the cotton mixing machine main body 1, so that negative pressure is formed in the cotton mixing machine main body 1, and the negative pressure device can be simply a negative pressure fan. Through such setting after, negative pressure device opens, forms the negative pressure in mixing drum 8, and the air is supplemented inwards by feeder hopper 3, consequently can effectually avoid flying and dust phenomenon, and filters the back through stainless steel filter screen 32, and impurity, garrulous fibre etc. can be taken out through shaft hole 31, axle chamber 30 and pump drainage mouth in proper order, carry out subsequent processing. It should be noted that, for the sake of clarity, the installation groove 17 is shown in fig. 2, which is more concave, and actually, the installation groove 17 with a convex shape should be adopted as much as possible to ensure the smoothness of the air flow and the impurities.

According to the invention, if the negative pressure equipment with stronger suction force is adopted, on one hand, impurities such as broken fibers can be further inhibited from overflowing from the feed hopper 3, and on the other hand, a thrust towards the inside of the cotton mixer main body 1 can be generated on fiber raw materials, so that the feeding is smoother. In addition, when the suction force is high, a pushing force towards the inside of the mixing drum 8 is generated from the fiber inlet 12 of the mixing drum 8, and under the double action of the pushing force and the centrifugal force, the fibers inside the mixing drum 8 are in a suspension-like state, so that the fibers are more conveniently mixed.

In order to further improve the safety of the present invention, a first safety valve 33 communicating the inside and the outside of the mandrel 7 is further provided on the circumferential surface of the mandrel 7 near one end of the negative pressure device, and a second safety valve 34 communicating the inside and the outside of the mixing drum 8 is provided on the end surface of one end of the mixing drum 8. With such a configuration, once the feed inlet 4, the shaft cavity 30, the shaft hole 31, etc. are blocked, the negative pressure device is in a continuous high-load state, and at this time, the first safety valve 33 and the second safety valve 34 can be opened to supplement the external gas, thereby preventing the negative pressure device from being burnt out. And the staff can also judge the position of jam according to the states of the first safety valve 33 and the second safety valve 34, thus reducing the difficulty of maintenance.
